The .30-30 Winchester (or "thutty-thutty") 
was the first smokeless powder cartridge, and was 
designed specifically for the 1894 Winchester 
rifle, the most long-lived of that series of 
lever-action rifles memorialized in the Hollywood 
western.  The .30-30 achieved great popularity as
a basic, inexpensive deer cartridge.

    Because of the strong association with these 
older lever rifles, the .30-30's reputation for 
accuracy has suffered a bit, but when chambered 
in a high-quality bolt-action or single-shot 
rifle, it will hold groups as tight as the best. 

    The .30-30 Winchester is usually encountered 
with flat-nose bullets, because of the tubular 
magazines of all of the above-noted lever-action 
rifles...  a round- or sharp-pointed bullet might 
act as a "firing pin" during recoil for the 
cartridge in front.

    The .30 Remington is basically a rimless 
version of the .30-30 Winchester, with virtually 
identical ballistics.
